How to fix libv8 "bad version" error when using mini_racer
March 10, 2020
TL;DR
Run bundle update mini_racer
The Issue I Experienced
I’ve been dealing with issues on my Mac for a while, so yesterday I decided to give in and wipe it. I upgraded to MacOS Catalina, then wiped my partition and did a fresh install.
In a few hours, I had almost everything running. Today, I tried to run bundle install to setup a Rails project’s dependencies and I was greeted by this:
Error: Command 'cipd ensure -log-level error -root/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor-ensure-file /var/folders/9l/2jz0cz8x56nbz806ty1fwwkh0000gn/T/tmpDPKTcT.ensure'returned non-zero exit status 1**\_\_\_\_** running 'cipd ensure -log-level error -root/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor-ensure-file /var/folders/9l/2jz0cz8x56nbz806ty1fwwkh0000gn/T/tmpDPKTcT.ensure'in '.'Error: failed to resolve package version (line 5): bad version (not an instanceID, a ref or a tag): "M56jPzDv1620Rnm\_\_jTMYS62Zi8rxHVq7yw0qeBFEgkC".Running: gclient rootRunning: gclient config --spec 'solutions = [{"url": "https://chromium.googlesource.com/v8/v8.git","managed": False,"name": "v8","deps_file": "DEPS","custom_deps": {},},]'Running: gclient sync --with_branch_headsTraceback (most recent call last):File"/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor/depot_tools/fetch.py",line 306, in <module>sys.exit(main())File"/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor/depot_tools/fetch.py",line 301, in mainreturn run(options, spec, root)File"/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor/depot_tools/fetch.py",line 295, in runreturn checkout.init()File"/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor/depot_tools/fetch.py",line 137, in initself.run_gclient(\*sync_cmd)File"/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor/depot_tools/fetch.py",line 82, in run_gclientreturn self.run(cmd_prefix + cmd, **kwargs)File"/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/vendor/depot_tools/fetch.py",line 71, in runsubprocess.check_call(cmd, **kwargs)File"/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py",line 190, in check_callraise CalledProcessError(retcode, cmd)subprocess.CalledProcessError: Command '('gclient', 'sync','--with_branch_heads')' returned non-zero exit status 1/Users/brandoncc/.rbenv/versions/2.5.7/lib/ruby/gems/2.5.0/gems/libv8-6.7.288.46.1/ext/libv8/builder.rb:79:in`block in setup_build_deps!': unable to fetch v8 source (RuntimeError)
There are two important lines here:
Error: failed to resolve package version (line 5): bad version (not an instance ID, a ref or a tag): “M56jPzDv1620Rnm__jTMYS62Zi8rxHVq7yw0qeBFEgkC”.
and

I tried every solution I could find for libv8 not compiling on a Mac. Most of them looked a lot like this one:
$ brew install v8@3.15$ bundle config build.libv8 --with-system-v8$ bundle config build.therubyracer --with-v8-dir=$(brew --prefix v8@3.15)$ bundle install
The Solution
Nothing I did resolved my issue…until I found my way to
this comment,
which made me wonder if mini_racer needed to be updated in order to be
compatible with
MacOS Catalina.
I ran bundle update mini_racer, and sure enough… my bundle installed!
Thank You, Friend
Thanks for stopping by, I really hope this helped you!
